The conduit 11 may be made in ,tivo sections, one

(11) section secured to the batch tank 10' and extending inwardly therebelow and the other (1.1) integrally formed with the Wall of the head 12. Vfhe'fn'the conduit 11 is constructed this manner, the sections are detachably connected a suitable'c'oupling 13 in a liquid tight 'inanner.

The valve 19 is connected to,a stem 20, which extends upwardly through the pipe 17 and has connected to it a float 21 of anyp'rcferred form of construction. YVhe'nthe material is supplied to the tank 10, the float rises With the material carfies wit it the valv 19 nt l th t r closes against the seat 18,'.thus shutting off the supply-ofthe material. The floatZl r ferably ed i t ly qime e t tha f m $20. so that may be positioned thereon ey d sir d hei t d hu ca se the dee s of the valve against its seat vlhen the level 0f th m ri eache the-d s r 'h i h depen ng tre th Quant y o t mat ii ll tQ tll eiliyiregiilatin'g the quantity of the inate rial to be supplied to the treating apparatus 1, 22 indicates an opening formed in the bottom of the tank 10 to'permit the material to flow therefrom through the conduit 11 into the freezing cylinder 2. 23 indicates a casing or housing member having a chamber23 to receive and support a valve 24 and ports or openings 23", 23 23, 3", and provided with a conduit :ection to which theouter or free end of the section ll is connected. As shown, (1) the pipe section is connected to the openings 23, c 3, so that when the valve 24 is in one position (see Fig. 2) with the opening 24 theretl'irough in registry with the openings 23, 23, the material will flow from the supply pipe 14: through the casing member 23, valve 24, pipe section 15 to the pipe 17 and (2) the casing member 23 is so arranged that the opening 28 connects with the opening 22 and the opening 23" is connected with the pipe section 25, so that when the valve 24 is in theposition shown in Fig.

5, it will cut off the supply of the materialthrough the pipe section 15 and permit the material in the tank 10 to flow therefrom through the opening 22, openings 23*, 23 conduit sections 11 11 to the cylinder 2.

From the foregoing description it will be seen that the valve 24 may be positioned to (1) close the discharge passage from the tank 10 and permit the flow of the material from the pipel t into the tank 10, or (2) shut off, the supply of the material to the tank 10 and permit the discharge of the material therefrom to the cylinder 2. The valve 24 is provided with a stem 26 carrying an arm 27 to which a rod may be pivotally connected. The rod preferably extends to a point adjacent the front end of the machine where it may be conveniently operated.

As shown in the drawings, the pipe sec tions or conduits for the material are prefcrably connected together by couplings 28, the ends of which open and closed by plugs 29, this arrangement permitting, the conduits to be easily and properly cleaned.

30 indicates a strainer which may be provided for straining the material as it flows through the opening 22. The strainer may be of any desired construction, but preferably comprises a cylindrical member having a reduced lower end which fits into the opening 22. The bottom of the tank 10 is inclined downwardly towards its rear end and the discharge opening 22 is arranged between the material inlet pipes 17 and the rear end of the tank 10, so that all of the material constituting a single charge or batch will flow out of the tank 10.

Where the invention is embodied in a mechanism associated with an ice cream freezer, the material supplied by the pipe 17 will be milk or cream used for making ice cream, but where the mechanism is associated with other apparatus, other kinds of liquid materials may be used.

To those skilled in the art of making apparatus or mechanism of the class described, many alterations in construction and widely differing embodiments and applications of my invention will suggest themselves without departing from the spirit and scope thereof. My disclosures andthe description herein are purely illustrative and are not intended to be in any sense limiting.

\Vhat I claim is:

1. In apparatus of the class described, the combination with a batch tank, of a material supply pipe leading thereto, a discharge pipe leading from said tank, means controlled by the rise of the material in said tank for shutting oil the supply of material thereto through said supply pipe, a casing member interposed in said sup ply pipe and said discharge pipe and provided with pairs of openings connected therewith, respectively, and a valve in said casing member having an opening through it for controlling the flow of the material either through said supply pipe or through said discharge pipe.

2. In apparatus of the class described, the combination with a batch tank, of a material supply pipe leading thereto, a discharge pipe leading from said tank, means controlled by the rise of the material in said tank for shutting off the supply of material thereto through said supply pipe, a casing member interposed in said supply pipe and said discharge pipe and provided with pairs of openings connected therewith, respectively, and a rotary valve in said casing memher having an opening through it for controlling the flow of the material either through said supply pipe or through'said discharge pipe.

3. In apparatus of the class described, the combinationwvith a batch measuring tank, having a bottom inclined toward one end, of a material supply pipe connected to the bottom of said tank, a discharge pipe connected to the bottom of said tank, between the connection therewith of said supply pipe and the lowermost end of the tank, means controlled by the rise of the material in said tank for shuttitng off the supply of the ma terial thereto through said pipe, a casing member interposed in said supply and discharge pipes and provided with pairs of openings connected therewith, respectively, and a valve in said casing member for controlling the flow of material through either said supply pipe or said discharge pipe.

In testimony whereof, I have hereunto subscribed my name.
